Eastern USA/Mid Bottom Bracket

This bottom bracket will only work in bikes that have either mid or American bottom brackets. These bearings come ready to install in American b.b. frames, but can easily convert to fit mid b.b. frames. You just need to remove the bearing from the outer shell; it's best to go to your local Eastern Bikes dealer to get this done. Plus, you never know what new goodies they may have in store. Most importantly, never forget to rock on with your bad self.
